General :: Change Bootloader Prestigio PMP3670b
May 8, 2014
I already have root permission on ClockworkMod Android.Initially I tried to reinstall OS to Android that I build from source code. But device hasn't got fastboot. So I decided to start from the bottom.
Current problem is that I have to locate UART on my device. Can't provide a photo of its board.URL....Processor is AllWinner A13, have found its data sheet. UART RX and TX pins are 151 and 152, 125 and 124, 13 and 12, and how to connect to it.

I cannot change the boot loader of the huawei u8230 android 2.1 A1 branded, carrier lock unlocked.I was able to install z4root.apk and was able to get temporary root with the following command
Adb shell
Su
#
Then I tried to install recovery-clockwork-3.1.0.1-u8220.img with install-recovery-windows.bat and with fastboot command Fastboot flash recovery recovery-clockwork-3.1.0.1-u8220.img but both did not work, the bootloader is still the original. What can I do to change the bootloader? Do I need permanent root? How to I get permanent root?

All information I found (perhaps I lookup with wrong keywords) is about unbricking the phone or other manufacturers tablets but once someone rooted the device and installed a modified rom but then playing with fastboot or some download managers, etc.
1. I wanted to revert back to 4.1 JB soft for my tablet as I found the most recent update messing up with 3G connectivity despite the fact the manufacturer prepared the update to improve 3G... anyway
2. I run the RKBatchTool 1.5 the device was connected properly as I did before when upgrading from ICS to 4.1 JB.
3. Unfortunately, just before the end of downgrading something went wrong (please see the below log) and now booting up the device fails. At first it displayed some linux script about trying to recover, then prestigio screen appeared just to show in a second a dead android robot with an exclamation mark.
14:57:28 504Rockchip Batch Tool v1.5.3.0 start run
15:02:16 091Rockchip Batch Tool v1.5.3.0 start run
15:05:33 769Rockchip Batch Tool v1.5.3.0 start run
15:58:23 292**********Upgrade Start Total<1>**********
15:58:23 307<Layer 5-3> Test Device Start
[code]....
4. I tried a combination of volume up and power button but still no luck.
How can I bring the live back to the device that was not rooted. I have an external SD card. I loaded an original image from prestigio but I guess I need something else done so it actually boots from the SD and recovers the ROM to the internal memory.

since I own a Neo V which is locked, and the service menu in the phone says that the Bootloader cannot be unlocked. if I unlock my SIM lock(probably with TurboSIM, since thats the cheapest solution), would that enable me to unlock my bootloader, and start the real modifying of my phone?

I want to restore official Xperia S ROM, but I need to relock my bootloader (or maybe not ), so can I do this on CM10 ROM, which needs to have unlocked boot loader?

I have LK bootloader source code which I need to build and flash to a Nexus 5 device.
* I got the source code from the Code Aurora website
* I made a guess which branch is the stable branch I need, because I found no mention of it anywhere (I took "kk_2.7-stable", where kk means kitkat)
* On a Debian 7 stable machine, I installed a GCC cross compiler from Deb packages built using Emdebian tools
* I made a guess which target to compile, because the exact chip name didn't have its own: I use msm8960
* I created some symlinks to the cross-building tools because the makefile and the debian cross-building tool names are different
* I ran 'make msm8960' and the build was successful (I also tried earlier with NDK prebuilt GCC but it failed)
* I got a bunch of files with no idea what to do with them
* I attached the device to the computer and re-flashed the stock bootloader to make sure it works
* I checked the fastboot screen: Bootloader unlocked, secure boot is on
* I tried flashing the 'lk' binary file I got from the build process, but fastboot says:
sending 'bootloader' (1702 KB)...
OKAY [ 0.239s]
writing 'bootloader'...
FAILED (remote: invalid bootloader image
)
The size of the file is much smaller than the size of the stock bootloader, but I don't know if it matters or what exactly I need to flash. I did a lot of web search, including here on XDA, but found no evidence of struggling with flashing the bootloader.
How do I flash the bootloader after I build it?

My Lava Mtab MG7 has become locked due to too many wrong pattern attempts. I can't log into the Google account to unlock it. I wanted to enter recovery mode to wipe data (hard reset). But I don't know the combination of key presses to enter the bootloader. I have tried the following:
1. Vol Up + Power
2. Vol Down + Power
3. Vol Up + Vol Down + Power

I've been following the instructions on the HTCdev website for unlocking the bootloader on my HTC sensation XE. Ive made it to the last step and acquired the unlock code from HTC. I then copied that to my computer and followed the last step "fastboot flash unlocktoken Unlock_code.bin" but I get an error message in the CMD promt "remote: unlock token check failed"
I have made sure that the .bin file is in the correct directory (c:Android).I have USB debugging enabled and fastboot disabled.

i want to know if it's possible to root an Android without unlocking the bootloader. My problem is I don't want anything wiped off the phone. I'm trying to get past the lock screen, because I found this phone in the street, so I want to get the numbers in it to try and return it. I've heard you can bypass the lockscreen if it's rooted. It's a Samsung Galaxy S Mesmerize, (or Fascinate).

i recently broke my last phone, so i had it replaced and this one is running 2.3.6, i tried using that black white screen (cmd?) with the options ex:
1. unlock root etc.
2. CWM install/root etc etc. x. debugging etc
but no luck. When i reach the rsd lite portion of the first section, my phone just boots up into the os and rsd lite gets cancelled. ( i chose 2.3.4)when i first got it, i could do everything fine, but i couldn't boot after installing 3 different roms. but when i install clean software it works just as it should

Now that the mempodroid hack based on the memory leak discovered by Aedla has been blocked (since about kernel 2.6.42, and android 4.0.3), are there any remaining ways of getting root access without re-flashing the bootloader? Alternatively, any pointers to how I would find (or build) a bootloader for a tablet based on rockchip RK29 board (for which I'm unlikely to be able to get detailed documentation)? Or is there any way to downgrade the kernel without root access?

I successfully unlocked the bootloader on my xperia x8 via flashtool put on custom kernel nAa 14 and miniCM7 Yay.Everything is fine apart that I want to change network because they have much better deals etc.I went to the 3 network shop and tried to put in the Sim, it took it in loaded but wouldnt register with the network , in fact I tried last week when I was on stock kernel and gingerxperia and it asked for ''unlock code'', today it didn't ask for unlock code took it in but wont register.I guess there must be some sim lock or something.
Maybe it is unlocked but something to do with Radio pehaps nonetheless my current Network works fine.here's my S1 LOG if any good. after unlocking BL of course
